Title
Post Snippets <= 4.0.19 - Authenticated (Administrator+) Stored Cross-Site Scripting via Import
Summary
The Post Snippets plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 4.0.19. This is due to insufficient output escaping of imported snippet content when rendering JavaScript variables in the post editor. Specifically, the `jqueryUiDialog()` method in `WPEditor.php` embeds snippet content directly into JavaScript string literals without escaping double quotes (the quote-escaping code on line 214 is commented out). When snippets are imported via the Import/Export feature, the content bypasses WordPress's `wp_magic_quotes()` (which would otherwise add protective backslashes), allowing double quotes in snippet content to break out of the JavaScript string context. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts via a malicious import file that execute whenever any administrator accesses a post editor page. Please note that this does not affect single-site installations as administrators already have the `unfiltered_html` capability.

Cuando los fragmentos se importan a trav\u00e9s de la funci\u00f3n de Importaci\u00f3n/Exportaci\u00f3n, el contenido omite la funci\u00f3n \u0027wp_magic_quotes()\u0027 de WordPress (que de otro modo a\u00f1adir\u00eda barras invertidas protectoras), permitiendo que las comillas dobles en el contenido del fragmento salgan del contexto de cadena de JavaScript. Esto hace posible que atacantes autenticados, con acceso de nivel de Administrador y superior, inyecten scripts web arbitrarios a trav\u00e9s de un archivo de importaci\u00f3n malicioso que se ejecutan cada vez que cualquier administrador accede a una p\u00e1gina del editor de entradas.

This is due to insufficient output escaping of imported snippet content when rendering JavaScript variables in the post editor. Specifically, the `jqueryUiDialog()` method in `WPEditor.php` embeds snippet content directly into JavaScript string literals without escaping double quotes (the quote-escaping code on line 214 is commented out). When snippets are imported via the Import/Export feature, the content bypasses WordPress\u0027s `wp_magic_quotes()` (which would otherwise add protective backslashes), allowing double quotes in snippet content to break out of the JavaScript string context. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts via a malicious import file that execute whenever any administrator accesses a post editor page. Please note that this does not affect single-site installations as administrators already have the `unfiltered_html` capability."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
